Massive sub pumps or cut into return line for skimmer?

[Myka]

Oh I see now...sorry, didn't look close enough the first time. The line with the ball valve is the return from the pump to the sump. So where's the skimmer pump and the intake then? Is that pump the pump that is manufacturer suggested to use?

The baffles aren't to slow the water down. The baffles are simply to filter out the microbubbles. If microbubbles get to the return pump the pump will chop them up even more and send them up to the display which is ugly and irritates corals.

Steve, it's a Beckett skimmer IIRC, that's why such a big pump.
